Cellulose fibers removed from water plants, Elodea Nuttallii, were refined using commercial enzymes, pectinase “PL AMANO”, and the influence of the treatment on the α -cellulose content and the molecular weight for refined ones were investigated. At the optimal treatment condition, the α -cellulose content of ca. 80 % and the viscosity-average molecular weight of ca. 237, 000 were obtained. These low values were mainly due to the low maturity of cell walls of the water plants. A severe enzymic treatment lowered the molecular weight since the commercial enzymes slightly have β -gulucosidase activity.
